Recent studies of individuals with cervical SCI show substantial cortical reorganization can occur after the injury, but neural substrates of motor learning after tendon transfer have not been studied. For these patients, very little is known about what functional brain changes accompany improved performance in response to additional intervention. The Br to FPL transfer alters the central feedback from the periphery and may permit new or adaptive neural pathways that can achieve greater functional use of the tendon transfer. Neuroimaging techniques, such as functional magnetic resonance imaging (fMRI) have become important tools for understanding plasticity in the neuromuscular system and for assessing the neural underpinnings of successful novel interventions. The objective of the proposed study is to identify the neural pattern that is associated with the best functional outcomes (highest pinch force) after Br to FPL transfer. The investigators will use fMRI and functional performance measures to find neural predictors and correlates of muscle re-education. That is, the investigators expect that successful postoperative muscle re-education will depend on increased cortical drive to the transferred Br in combination with new synergists, and this will be reflected in the neural imaging results.
